Fast magnetic resonance force microscopy with Hadamard encoding

We present a spatial encoding technique for magnetic resonance force microscopy that allows for a much enhanced image acquisition rate. The technique uses multiplexing, based on spatial Hadamard encoding, to acquire several slices of the image simultaneously and at an undiminished signal-to-noise ratio. We demonstrate an improvement in imaging time by a factor of 7.6, and further advances can be expected. © 2007 The American Physical Society.
